Little Truck LoverMay 21, 2026on Reefs RC SX30 Aluminum Servo Arm & Ball Stud (SCX30)

It looks cool but the ball stud contacts the 3rd member on the axle and limits the servo throw. Eventually I'll get around to milling about .750mm off the back of the control arm to move the ball stud forward a bit. Lot of work for a $10 servo horn but at least it can be corrected. Until then it's using the stock plastic horn that came with the SX30 servo.
